I've been fascinated with this piece of Americana history for more than 20 years.  The reading material that inspired my curiosity is is quite diverse yet very focused.  With authentic tales and the story telling from one of the most prolific hobo writers, Leon Ray Livingston, aka. A No1, one can actually grasp a true sense of this era.  I felt the same about the Once a Hobo, by Monte Holmes, Jack London, and the others also listed below.
